HAC RATING
The FCC has created a rating system for cellular phones
regarding their HAC-related performance. This rating helps
consumers with hearing disabilities to find phones that work
well with their hearing aid devices. The HAC rating and
measurement procedure are described in the American
National Standards Institute (ANSI C63.19-2011) contains
two rating standards:
an “M” rating from 1 to 4 for hearing
aids operating in microphone mode,
and a “T” rating from
1 to 4 for hearing aids operating in tele coil mode. M-Rating
stands for Microphone rating and indicates the amount of
reduction of RF interference between the telephone and
the hearing aid in acoustic coupling mode (also called
microphone mode). Phones rated M3 or M4 meet FCC
requirements and generate less interference to hearing
devices set in microphone mode. T-Rating stands for tele
coil rating and represents inductive coupling with hearing
aids that are operating in telecoil mode. A tel coil is a small
piece of tightly wrapped wire, built into some hearing aids.
While the microphone of a hearing aid picks up all sounds,
the telecoil only picks up an electromagnetic signal from the
telephone. Thus, users of telecoil-equipped hearing aids
are able to communicate over the telephone without the
amplification of unwanted background noise. Phones rated
T3 or T4 meet FCC requirements and generate less
interference to hearing devices set in telecoil mode. A
combination of M-rating and T-rating defines the final HAC
rating and is a deciding factor in selecting cellular phones
for people with hearing problems. A HAC compliant phone
could be rated:
• M3/T3
• M3/T4
• M4/T3
• M4/T4
its resistance to interference. The best way to evaluate
the suitability of the phone is to try it with the intended
hearing aid device.
The model XP3800 have been tested for hearing aid
device compatibility and complies with the Federal
Communications Commission (FCC) requirements.
These devices are rated M3/T4.
